Thiel Owners


I just scored a sweet pair of CS 2.4SE loudspeakers. Anyone else currently or previously owned this model?
Owners of the CS 2.4 or CS 2.7 are free to chime in as well. Thiel are excellent w/ both tubed or solid-state gear!

Keep me posted & Happy Listening!

jonandfamily - we look forward to your report. Here's some additional back-story about that soft dome.

We developed that UltraTweeter for the CS5 in 1988. It had all of Jim's advanced techniques, and exceeded our expectations. The CS5 had woven lower Kevlar drivers, and if an appropriate soft upper midrange driver had been found, we would not have gone to aluminum. However, the MB Quart 2" aluminum dome did the job better than anything else, and we didn't have time to develop our own driver for that use. Market pressure. The aluminum tweeter had more predictable response particulars and the metal domes dissipated heat better. That's where we went.

When trickling that tweeter down to the CS2.2 we reconsidered the fiber dome to mate with the pulp midrange. Jim went with the CS5 tweeter and gradually migrated to all aluminum diaphragms rather than all Kevlar / fiber / etc.

So, I consider that soft dome tweeter as native - it was co-developed with the hard dome and should be very good, with possibly some advantages. The only one I've ever heard was in comparative evaluation during 2.2 development around 1989. I'll be getting a pair for comparative measurements and listening tests.

As a general caution, heat dissipation is a big deal. The soft dome don't be a heat dissipator like the aluminum dome is. Don't over-drive it.

Keep us posted.


I received the soft dome tweeters, installed them in the 3.6s and listened throughout the weekend. Early on, they were fatiguing with increased sibilance, but seem to be approaching the original sound either from mechanical break-in or psychoacoustical break-in. Vocals, especially female seem to be moved a little forward. I expect with more play time, these 3.6s will continue to reside in my main system. Rob Gillum agrees they need break-in.



Good to read a preliminary report. I have no doubt that Rob treated your situation right.  Keep me posted with the break-in. Enjoy the Music.


Happy Listening!
